Diseases that increase the eosinophil count (eosinophilia) generally fall into the categories of allergic disorders and parasitic infections.
Diseases Associated with Elevated Eosinophil Count
Eosinophilia, or a higher-than-normal eosinophil count, can be indicative of several underlying health issues. These issues trigger the body's immune system to produce more eosinophils. Here's a more detailed look at the types of diseases associated with increased eosinophil counts, incorporating information from the provided reference:
Allergic Disorders
Allergic reactions are a significant cause of eosinophilia. Examples include:
- Drug Sensitivities: Adverse reactions to medications can trigger eosinophil production.
- Asthma: Both general asthma and eosinophilic asthma are frequently associated with elevated eosinophil levels.
- Allergic Rhinitis: Also known as hay fever, this condition involves inflammation of the nasal passages due to allergens.
- Atopic Dermatitis: A chronic skin condition characterized by itchy, inflamed skin.
Parasitic Infections
Certain parasitic infections, especially those where the parasites invade body tissues, often lead to eosinophilia.
